About
At Focal Partners, I’m building three SaaS products for bookings, loyalty, and payments. For TuBarberIA, I built a subscription SaaS and marketplace for barbershop bookings and sales with Next.js, TypeScript, tRPC, Prisma, and Supabase.
I extended the shared architecture into a management SaaS and booking marketplace for car-service businesses, reusing three shared monorepo packages to cut delivery time. At Lazoo, I led the v2 rebuild of a loyalty SaaS with Apple and Google Wallet passes and QR check-ins, shipping fixes and features to the v1 production app.
My earlier work includes maintaining a metallurgical balance platform for CMP mining operations and delivering software for logistics, ticketing, fintech, and public-sector systems. I’ve also worked with remote U.S. teams and used AI-assisted workflows, including Cursor and Claude Code.
